Terror Behind the Walls, America’s largest haunted house, is called “perfect for Halloween” by The New York Times, named #1 in the nation by Forbes, and featured on NBC’s TODAY Show. Terror Behind the Walls takes place inside the massive, castle-like walls of Eastern State Penitentiary and is consistently ranked among the top haunted attractions in America.
All proceeds from Terror Behind the Walls benefit the preservation of Eastern State Penitentiary, a National Historic Landmark. Terror Behind the Walls does not affect operation of the historic site, which remains open for tours every day from 10:00 am to 5:00 pm.
